Isle of Man Energy is reminding people not to worry if they see the emergency services racing to its facilities at Douglas Harbour this afternoon.
The company says it's holding an emergency response exercise at its gas sphere site from 2pm.
Involved will be vehicles and staff from the Fire and Rescue Service, Civil Defence, Coastguard, Health and Safety, paramedics and police.
The 90-minute training drill is designed to test emergency procedures and the way emergency services work together.
